My invention relates'to improvements in suction sweepers particularly of a.1 n otorvdriven brush type and has for one Ob ect to mg and moving parts such that the height of themachine will be a minimum. Another object is to provide an apparatus which will be light, com act, -durable and, easily hanpear from t-lon.

time to time in-this specificaparatus in which the combined fan and motor housing is so tilted that the overall hei ht were-vertical or if the motor and fan were horizontal because in vertical position the great length 'ofthe motor may makethe hei ht of .the apparatus excessive and in horizontal position the great diameter of the fan housing may make'the height of the app'aratus excessive, and by tilting them the either of the 'two above mentioned positions.

with-the aperture B in the front wall of the fan chamber. It happens in this case that the fan chamber passagewayand nozzle are all in one integral casting, though they might be separate. B is a brush mounted for rov tation in the nozzle so arranged that the bristles B extend down slightly below the plane of the open mouth. B is a pulley on the brush, driven b a belt B which in turn is driven by a pul eyB on the motor shaft A so that when the motor rotates the fan to suck air inthrough the open mouth and discharge itinto the ba'g' it simultaneously drives the b1' 'ush. The front'wa-ll of the passage B isia'pertured as at B and this apertureijis closed by the removable housing B", the-parts being so'a'rranged that when it. is desired" to. draw air into the fan chamber througha'hose'rpipe'an adapter of a suitable type-not here illustrated may be passed in v t rough the opening B", to close the opening 13 and therebydisconnect the suction nozzle v v ,which pro'ect downwardly from the fan by like c aracters housing an rearwardly from the nozzle. The studs C upon which the rollers are mounted, are 'slidable in slots C in the lugs G.

movement in the slot ceases and so the roller .may be locked in adjustable position to control the height at which the nozzle stands above the floor.. v y It will be evident that while I have shown an operative device, still many changes mightbe made both in size, shape and arrangement of parts without departing materially from the spirit of my invention, and I wish, therefore, that my drawings be regarded as in a sense at least very diagrammatic.

The use and operation of my invention are as follows When current is supplied to the motor to drive itin the usual manner, the fan rotates and draws air in through the open suction nozzle to carry off dust and dirt from the floor covering which is being cleaned The brush,

When the. thumb screw C is tightened'up,

being driven by the rotation of the motor shaft, brushes and beats the covering so as to asist in. loosening the dirt.

The peculiar inclination of the axis of ro'-. tation of the clination of the motorand fan housing, does not in any way vafl'ect the operation of the device but, as previously indicated, the total hei ht of the device is less than it' would be if the axis of rotation were horizontal or vertical because the height .from' the. plane of the suction nozzle to the point which I have indicated by 'Xin less than the diameter .0 lei: h of the motor shaft.

e fan casing or e. motor is, of course, housed but the housing is a partof the motor-and it-isanism for producing art of the motor, t

.of the essence of the scheme that the housing fof the motor is so positioned as to copperate with v the other parts in producing the. height of one part ofthe mechthis result is the lower at is to say, the'housing 1n the plane of the nozzle.

If the motor, using that term to minimum indicate 7 'the motor roper and also its housin or tatably chambera fan chambergand a motor .ar-

casing, be' s ortened the total height 0 the suction cleaner can be reduced by tilting the fan chamber more sharply.
